ALBION OAK JONES, or BATTLE CREEK, MICHIGAN, ASSIGNOR To UNITED STATES MICHIGAN, A CORPORATION OF MICHI- WARM-AIR-R-EGISTER DAMPER OPERATOR.

Application filed January 26, 1922. Serial No. 531,984.

This invention relates to warm air register damper operators, by which is meant the device intended to be directly actuated by the hand of the person desiring to control the flow of warm air through the register and into the room in the wall of which the register is situated. I It is the purpose and function of such devices to enable the person seeking to move the damper to arrange the same in any chosen position between full open position and its closed position, and to sufliciently hold the damper in its adjusted position. by frictional contacts set up between parts of the device itself. To this description of devices the present invention belongs,.and it comprises a register damper operator fashioned from a single piece of bendable and elastic sheet metal bent upon itself to form certain defined members or elements having special construction and operation whereby it is believed material economy in manufacturing is attained, and that the device may be very quickly placed in position and as readily removed for repairs or replacement, and that it is especially effective andreliable in its action and service.

The construction and arrangement of the parts of this invention are shown in the accompanying drawings of which Fig. 1 represents a vertical section of a warm air register box having this invention applied thereto and illustrating the position in which the device is located upon the register. Fig. 2 is a vertical section, approximately full size, showing a portionof the open-work .lattice or front of the register with the damper pivoted thereon and this invention supported thereby. Fig. 3 is a front view of this invention by itself. Fig. 4 is a back view. Fig. 5 is a vertical section on the broken line 5-5 of Fig. 4. In all the figures after Fig. 1 the scale of drawing is.

0 work face plate or front B, which may be of any selected pattern, and may be removable or in one piece with the box. The usual opening in the front of the box through which the warm air passes outwardly is bounded by the inwardly turned flanges a as illustrated in Fig. 1. Thesel langes are particularly useful in warm air registers as they act to direct the fiow of air entirely through the opening in the front of the register box, and do not allow small streams of air to escape laterally which as a general thing results in dust streaks upon the adjoining wall or wall paper. By the use of the fiang'es'as shown that objection does not occur. r 7

As will be noted in Figs. 1 and 2, the pivotal connection 2; couples the damper C and the register front B, and the damper has the'slot 0 near thejtop. I

The front B of the'r'egister is provided with a pair of spaced ears near the top, one of which designated by the letter D is shown in Figs. 1 and 2. Those ears D support a pivot pin or bolt (1, which in turn pivotally upholds the device constituting the main subject-matter of this invention. This device comprises a single piece of bendable and elastic sheet metal bent upon itself to form a head E, which is the finger piece grasped by the fingers to actuate the damper. From the head there extends the curved and grooved body 6, as best illustrated in Figs. 3, 4, and 5, and the body has a pair of spaced ears F and 7, that are provided with corresponding openings for the passage of.

either side of the end of the body.

The single piece of metal of which this invention is made is also formed into the back piece H, and the back piece passes in a curving direction between the ears of the body curving towards the body and then curving outwardly and downwardly and terminating near the end of the body 0 where it is provided witha pair of lugs h and h as shown in Figs. 2 and 5. These lugs project towards the lugs G and g of the body 0 as illustrated. It will be noted in Figs. 1 and 2 that the back piece H asses through the slot 0 in the damper, an that the ends and lugs of the body and back piece are arranged upon opposite sides of the damper.

sired position into which it may be adjusted,

between its full open position, or partly openas it appears in Fig. l, or closed as it appears in Fig. 2. As stated, this invention is made of metal more or less elastic, and, considering Figs. 1 and 2, it will be understood that the ends of the parts re ferred to by the letters G and h are elastically separable to a certain extent. The

reason for this is that many persons in open-V ing and closing a register damper or plate such as the damper G, do so very roughly, often with the foot, and the elastlc capacity of this invention in a measure cushions the blows and prevents the bending of connected sheet metal parts. l

Having now described the special construction and arrangement of the parts of this invention, and explained the mode of its operation, What I claimis A warm air register damper operator, comprising a single piece of bendable and elastic metal bent upon itself to form a head, a curved and grooved body extending from the said head and provided with spaced ears located intermediately with respect to the said head and the end of the body, said ears having openings for the passage of a pivot pin, a curved and grooved back piece extending from the said head and passing between the said ears of the body and terininatingnear the end of the said body, a spring arranged across the said back piece and bearing-upon the said ears to spread the ears apart, a register front, a damper pivoted to the register front and passing between the said body and backpiece of the said damper operator, and the said register front having ears arranged against the said ears of the damper operator wherebythe said spring holds the 531d ears in frictional contact.

In testimony whereof I affix my signature.

ALMON OAK JONES.
